FIG. 5 is an exploded perspective view illustrating an assembly-type charging apparatus according to various embodiments of the present disclosure.

Referring to FIG. 5, the assembly-type charging apparatus may include the charger module 400 and a cradle 500.

The shape of the cradle 500 may be formed to correspond to the shape of a wearable device to be mounted while the shape of the charger module 400 may be maintained regardless of the shape of the wearable device. In order to effectively charge the wearable device, the location of a charger module mounting part 510 may be varied in the cradle 500 such that pins of the charger module 400 can be disposed for an electrical connection with pins of the wearable device.

In one embodiment, the charger module mounting part 510 may be disposed at the right half of the cradle 500 to hold the charger module 400 as shown in FIG. 5.

The cradle 500 may include the charger module mounting part 510. The shape of the charger module mounting part 510 may be substantially identical to that of the charger module 400. The size of the charger module mounting part 510 may be determined suitably for an easy attachment or detachment of the charger module 400.

The location of the charger module mounting part 510 may be determined in the cradle 500, considering an electrical connection between the charger module 400 and the wearable device.

FIG. 6 is a perspective view illustrating an assembly-type charging apparatus according to various embodiments of the present disclosure.

FIG. 6 shows the charger module 400, the cradle 500, and a power connector 610.

The assembly-type charging apparatus may hold a wearable device mounted on the cradle 500, allowing the wearable device to be electrically connected to the charger module 400. In order to prevent the detachment of the wearable device, the assembly-type charging apparatus may include a protruding part 530 formed at both lateral edges of the cradle 500.

The protruding part 530 may have a hook or the like for mechanically binding the wearable device. Alternatively, the protruding part 530 may merely operate, without using a hook, as a supporting bracket for preventing the detachment of the wearable device.

The power connector 610 may pass through the third hole 520 of the cradle 500 and the second hole 420 of the charger module 400 and then be connected to the external power connecting terminal 334 of the charger module 400 so as to supply electric power from any external power source.

The shape of an end part of the power connector 610 may correspond to that of the external power connecting terminal 334 of the charger module 400 such that an electrical connection can be easily and reliably made.

In one embodiment, the power connector 610 may have a USB form. Thus, the external power connecting terminal 334 may have a USB-type socket to receive electric power from the USB-type power connector 610.

In another embodiment, the power connector 610 may be configured to have an integrated cable form. Thus, the external power connecting terminal 334 may have a structure corresponding to the integrated cable form to receive electric power from the cable-type power connector 610.

FIG. 7 is a perspective view illustrating an assembly-type charging apparatus according to various embodiments of the present disclosure.

Referring to FIG. 7, the assembly-type charging apparatus may include a cradle 700, a charger module 710, and a power connector 720.

The assembly-type charging apparatus may hold a wearable device mounted on the cradle 700, allowing the wearable device to be electrically connected to the charger module 710. In order to prevent the detachment of the wearable device, the assembly-type charging apparatus may include a protruding part formed at both lateral edges of the cradle 700.

The protruding part may have a hook or the like for mechanically binding the wearable device. Alternatively, the protruding part may merely operate, without using a hook, as a supporting bracket for preventing the detachment of the wearable device.

The cradle 700 may be different in appearance from the above-discussed cradle 500. Namely, in order to accommodate different-type wearable devices, the cradle 700 may have a charger module mounting part disposed at the middle portion thereof and holding the charger module 710.

The charger module 710 may have a substantially cubic shape with round edges. Meanwhile, the charger module 710 may be formed of synthetic resin, thermoplastic polymer (e.g., ABS or polycarbonate), ceramic, wood, metal (e.g., polished aluminum), metal alloy (e.g., based on steel, stainless steel, titanium or magnesium), or any other suitable material.

The combination of the first and second housings forms the internal space of the charger module 710. In this space, the PCB, the charging terminal, the external power connecting terminal, and the like can be disposed and mounted.

Referring to FIG. 7, the charger module 710 may be connected with the cable-type power connector 720. Contrary to a USB type, the cable-type power connector 720 may disallow the detachment from the charger module 710 and maintain a continuous connection therebetween.

Meanwhile, although having different-type power connector, the charger module 400 and the charger module 710 may have the substantially same shape and the substantially same charging terminal Additionally, although having different shapes depending on the shape of a wearable device to be mounted, the cradle 500 and the cradle 700 may share the charger modules 400 and 710 having the substantially same shape.

Therefore, in case the wearable device is changed, it is only required to use the cradle suitable for the changed wearable device to perform a charging function without the need to purchase other charger module adapted to the wearable device. Namely, since charging the wearable device is allowed by using a common charger module and changing only the cradle, a consumer's burden of cost may be reduced.

FIGS. 8A and 8B are plan views illustrating the disposition of magnetic members in an assembly-type charging apparatus and a wearable device according to various embodiments of the present disclosure.

FIGS. 8A and 8B show an assembly-type charging apparatus and a wearable device 810. The assembly-type charging apparatus may include a cradle 800, a charger module 820, a magnetic member 832, and a protruding part. The wearable device 810 may include a charging pin 824 and a magnetic member 830.

In one embodiment, the protruding part of the cradle 800 may form a supporting bracket rather than a hook or the like for binding the wearable device. In this case, it is possible to prevent a scratch of the wearable device 810 and also prevent breakage of the protruding part. However, if the protruding part of the cradle 800 has no binding means such as a hook, the wearable device 810 may fail to be mounted stably on the cradle 800. Therefore, when there is any external shock, the charging pin 824 of the wearable device 810 may be out of contact with a charging terminal 822 of the charger module 820 due to the movement of the wearable device 810. Unfortunately, this may invite an unstable supply of electric power to the wearable device 810.

In order to more stably mount the wearable device 810 on the assembly-type charging apparatus, the magnetic member 832 may be attached to the cradle 800. Alternatively or additionally, for the same reason, such a magnetic member may be attached to the charger module 820 or the charging terminal 822.

The magnetic member 832 may be exposed to the outside of the cradle 800 or embedded in the cradle 800.

Similarly, the wearable device 810 may have a metallic plate or the magnetic member 830 embedded therein for a stable combination with the magnetic member 832 of the assembly-type charging apparatus.

In case of embedding the metallic plate in the wearable device, a sufficient attractive force is required for a stable combination with the magnetic member 832. For this reason, the metallic plate needs to have a sufficient thickness or area in the wearable device. This may, however, hinder a reduction in size of the wearable device.

In case of embedding the magnetic member 830 in the wearable device, a sufficient attractive force is required for a stable combination with the magnetic member 832. Since an attractive force between the magnetic members is greater than that between the magnetic member and the metallic plate, using the magnetic member may be more effective for reducing the size of the wearable device than using the metallic plate.

In one embodiment, viewing down the assembly-type charging apparatus, the magnetic member 832 may be disposed at the left half of the cradle 800. Also, the charger module 820 may be disposed at the right half of the cradle 800.

Meanwhile, the charging pin 824 and the magnetic member 830 of the wearable device 810 may be disposed to correspond to the charger module 820 and the magnetic member 832 of the assembly-type charging apparatus.

In one embodiment, viewing down the rear side of the wearable device 810, the charging pin 824 corresponding to the charging terminal 822 of the charger module 820 may be disposed at the top left-hand portion of the wearable device 810. Also, the magnetic member 830 corresponding to the magnetic member 832 of the assembly-type charging apparatus may be disposed at the top right-hand portion of the wearable device 810. This disposition may allow the wearable device to be more stably mounted on the assembly-type charging apparatus and to be stably charged with electric power.

The above discussion is exemplary only and not to be construed as a limitation of the present disclosure. For example, type, disposition, number, etc. of the magnetic member may be varied by manufacturers.

FIGS. 9A and 9B are plan views illustrating the disposition of magnetic members in an assembly-type charging apparatus and a wearable device according to various embodiments of the present disclosure.

In one embodiment, the protruding part of the cradle 900 may form a supporting bracket rather than a hook or the like for binding the wearable device. In this case, it is possible to prevent a scratch of the wearable device 910 and also prevent breakage of the protruding part. However, if the protruding part of the cradle 900 has no binding means such as a hook, the wearable device 910 may fail to be mounted stably on the cradle 900. Therefore, when there is any external shock, the charging pin 924 of the wearable device 910 may be out of contact with a charging terminal 922 of the charger module 920 due to the movement of the wearable device 910. Unfortunately, this may invite an unstable supply of electric power to the wearable device 910.

In order to more stably mount the wearable device 910 on the assembly-type charging apparatus, the magnetic members 934, 935 and 936 may be attached to the cradle 900. Alternatively or additionally, for the same reason, such a magnetic member may be attached to the charger module 920 or the charging terminal 922.

The magnetic members 934, 935 and 936 may be exposed to the outside of the cradle 900 or embedded in the cradle 900.

Similarly, the wearable device 910 may have a metallic plate or the magnetic members 931, 932 and 933 embedded therein for a stable combination with the magnetic members 934, 935 and 936 of the assembly-type charging apparatus.

In case of embedding the metallic plate in the wearable device, a sufficient attractive force is required for a stable combination with the magnetic members 934, 935 and 936. For this reason, the metallic plate needs to have a sufficient thickness or area in the wearable device. This may, however, hinder a reduction in size of the wearable device.

In case of embedding the magnetic members 931, 932 and 933 in the wearable device, a sufficient attractive force is required for a stable combination with the magnetic members 934, 935 and 936. Since an attractive force between the magnetic members is greater than that between the magnetic member and the metallic plate, using the magnetic member may be more effective for reducing the size of the wearable device than using the metallic plate.

In one embodiment, viewing down the assembly-type charging apparatus, the magnetic members 934, 935 and 936 may be disposed respectively near the right, top and left edges of the cradle 900. Also, the charger module 920 may be disposed at the right half of the cradle 900 so as not to be overlapped with the magnetic members 934, 935 and 936.

Meanwhile, the charging pin 924 and the magnetic members 931, 932 and 933 of the wearable device 910 may be disposed to respectively correspond to the charger module 920 and the magnetic members 934, 935 and 936 of the assembly-type charging apparatus.

In one embodiment, viewing down the rear side of the wearable device 910, the charging pin 924 corresponding to the charging terminal 922 of the charger module 920 may be disposed at the top left-hand portion of the wearable device 910. Also, the magnetic members 931, 932 and 933 corresponding to the magnetic members 934, 935 and 936 of the assembly-type charging apparatus may be disposed respectively near the left, top and right edges of the wearable device 910. This disposition may allow the wearable device to be more stably mounted on the assembly-type charging apparatus and to be stably charged with electric power.

The above discussion is exemplary only and not to be construed as a limitation of the present disclosure. For example, type, disposition, number, etc. of the magnetic member may be varied by manufacturers.

When the wearable device 1000 is mounted on the cradle 1010, a charging terminal of the charger module 1020 keeps in contact with a charging pin formed on the rear side of the wearable device 1000 so as to perform a charging function.

In one embodiment, a magnetic member of the cradle 1010 is combined with that of the wearable device 1000 by means of an attractive force, so that the wearable device 100 can be stably mounted on the assembly-type charging apparatus.
